Western Australia’s Best-Rated Solar Installers: 2025

Who were the three best-rated WA solar installers for 2025 based on customer reviews published on SolarQuotes? See the winners here.

2025 winners for Western Australia followed a weighted calculation of customer reviews of solar installers operating in the state listed on the SolarQuotes website. This created a more level playing field for smaller companies with fewer reviews against their bigger competitors. All WA installers we have listed were analysed; not just those businesses part of the SolarQuotes network.

First Place –  Regen Power

Founded in 2003, Regen Power offers solar installations, battery storage systems and EV charging solutions and is headquartered in Canning Vale, Perth.

The company was built under the leadership of founding Managing Director Professor Chem Nayar, who prior to starting the company had accumulated decades in applied research and commercialisation of alternative energy sources. In 1988, Professor Nayar established the Centre for Renewable Energy and Sustainable Technologies Australia (CRESTA) at Curtin University and managed the Centre for 15 years.

Regen Power’s comment on taking out first place:

“Regen Power’s win reflects 22 years of putting customers first in WA—backed by quality engineering, transparent advice, and reliable after-sales support.

 

With more than 45,000 residential and 2,000 commercial installs, our focus is doing the basics exceptionally well: meticulous design, clean and safe installs, and prompt service when customers need us. We invest in local teams, audit our work rigorously, and only recommend products we trust. That combination of care, consistency, and accountability is what sets us apart—and why our customers keep recommending us.”

Some of what the many Regen Power customer reviews on SolarQuotes have had to say:

“From our initial contact to the installation and purchase of a solar battery the customer service and procedure used was simple and stress free. Paperwork for various grants and rebates were handle all by the team at Regen Power making it easy and seamless. We have used them for our PV system and now the battery and service has always been exceptional.” – Tracey

“This is one of the most reliable companies that I have ever come across! The whole sales, quoting and installation process was easy from beginning to end. All team members were polite and courteous. I was well advised of each step throughout the process, and they even completed all the necessary paperwork required by Synergy. Their after sales service is exceptional even one year on. I cannot fault Regen Power at all!” – Rose

“We did a lot of research before selecting Regen Power. We chose Regen based on its product selection, pricing, technical capability, service and responsiveness. Regen took care of all the details for us and we were not disappointed. Highly recommended!” – Phil.
